Positioning structure for umbrella runner

ABSTRACT

The invention relates to a positioned structure for umbrella runner, which is connected with two engaging slices on both sides and a sleeve is provided around. An annular groove is provided on top tube of the shaft of the umbrella. The sleeve can be moved upward and downward for swinging the slices to position the runner and the umbrella in stable opened state.

FIELD OF THE INVENTION

The present invention relates to an umbrella, which has an invented structure for positioning the runner in ease.

BACKGROUND OF THE INVENTION

A conventional umbrella is provided with an elastic bow in the shaft to position, its runner for maintaining the umbrella in opened state. It is known that the procedure to put the elastic bow into the shaft is very difficult and trouble. Moreover, a slot must be formed on the shaft for allowing top end of the elastic bow extending outward. This will decrease the strength of the shaft.

SUMMARY OF THE INVENTION

The present invention is to provide a positioning structure for runner of the umbrella, which provides a runner with engaging slices inside and a sleeve placed around the runner. And the runner can be stopped at right place for maintaining the umbrella in opened state very easily while the elastic bow is not necessary.

Now, accompanying with the following drawings, the character of the present invention will be described here and after.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please referring to FIG. 1 to 4, the present invention is mainly used on an umbrella having a shaft (4) composed of multiple tubes wherein each upper tube is larger than each lower tube. A runner (1) is provided around the shaft (4), which has the top tube with an annular groove (41). The runner (1) has both sides with a groove (11) for engaging with an inner protrusion (21) of a respective engaging slice (2), which is then capable of swinging.

A sleeve (3) is placed around the runner (1) and is provided with an inner annular ring (31) to contact with the slices (2). The sleeve (3) is engaged with the runner (1) by bottom hook (12) that the sleeve (3) can only move a slight distance outside the runner (1). When the umbrella is opened, as shown in FIG. 4, the runner (1) is in the right place and the sleeve (3) can be moved upward to push top end of the slice (2) swinging inward by the inner ring (31). The engaging end (22) of the slice (2) is then engaged with the groove (41) of the shaft (4) that positions the runner (1) in stable for keeping the umbrella being opened.

When to close the umbrella, the sleeve (3) is moved downward firstly to recover the slice (2) for releasing the engaging end (22) from the groove (41). Hence, the runner (1) can be moved down to close the umbrella.

The runner (1) of the present invention can be used on a prior known umbrella having a shaft with multiple tubes, wherein each upper tube is smaller lower tube and top tube is provided with an elastic bow (42). As shown in FIG. 5 and 6, the engaging end (22) of the slice (2) can be engaged with the extended top end of the elastic bow (42) that keeps the runner (1) position for maintaining the umbrella in stable opened state. In another embodiment of FIG. 7, it shows that the shaft (4) is provided with two apertures (43) on both sides for positioning the engaging end (22) of the slice (2). This modified structure is also claimed in the present invention. 

1. A positioned structure for umbrella runner having side grooves for engaging with two respective slices, which is capable of swinging and has upper engaging end, a sleeve placed around the rubber having inner ring to contact with the slice, and the sleeve being capable of moving upward and downward for swinging the slice to engage with shaft of the umbrella and to release from the positioning place.
 2. A positioned structure for umbrella runner as claimed in claim 1, wherein the umbrella has a shaft composed by multiple tubes, in which each upper tube is larger than each lower tube and top tube is provided with an annular groove for engaging with the engaging end of the slice to position the runner and the umbrella in opened state.
 3. A positioned structure for umbrella runner as claimed in claim 1, wherein the umbrella has a shaft composed by multiple tubes, in which each upper tube is smaller than each lower tube and an elastic bow is provided in top tube for engaging with the engaging end of the slice to position the runner and the umbrella in opened state.
 4. A positioned structure for umbrella runner as claimed in claim I, wherein top tube of the shaft is provided with an aperture on both sides for engaging with the engaging end of the slice to position the runner and the umbrella in opened state.
